Both are excellent handguns and either will serve you well!

That said, I do tend to favor the Tanfoglio Pistols, as they have better out of the box triggers due to a better Passive Firing Pin Lock design, and a bushingless Barrel to Slide Lockup.
Built like a proverbial Tank, they are hard to wear out! I've tried!
Also note that my personal preference is for the original Tanfoglio Small Frame, when it comes to the 9mm chambered versions.
Downside for the Tanfoglio Pistols has been that the Front Sight is molded into the Slide and not easily changed without Gunsmithing.
Upside for the TriStar Cz Clones has been a bit higher quality of machining and fit. Aftermarket trigger parts support form CGW, if you care about such things. I don't.
Out of the box reliabilty is a bit higher for the TriStar Pistols, but not by much.
Either will deliver excellent accuracy, provided the shooter will do their part.
